Her appearance could be a more dominant reflection of Kurenai. She has Kurenai's long, dark hair and her mysterious allure. However, she has Naruto's bright, determined look in her eyes. And she might have some of Naruto's more boyish features, like his strong jawline, which gives her a unique and striking look.
She could inherit Naruto's spiky hair, but in a darker shade closer to Kurenai's hair color. Her eyes might be a unique blend of blue and red, creating an almost purple hue. Physically, she might be tall like Naruto, but with Kurenai's grace and elegance in her movements.
She might have Naruto's blue eyes and Erza's red hair. Her face could have a combination of their features, with Naruto's cheeky smile and Erza's strong jawline.
She might have Naruto's blond hair and Sakura's green eyes. Her face could be a combination of their features, with Naruto's cheeky smile and Sakura's determined expression.
In such a fanfiction, Naruto's upbringing would be different. Kurenai could teach him her unique jutsu from a young age. The story might focus on how Naruto's personality, which is usually influenced by his loneliness as an orphan, would change. He could have a more stable family environment, which would impact his relationships with Sasuke and Sakura. There could also be new story arcs involving Kurenai's past and how it relates to Naruto's future.
Physically, she could inherit Bellatrix's tall and slender figure. However, she may carry herself with a bit more reserve like Snape. Her facial features could be a mix of both. Maybe she has Bellatrix's sharp cheekbones but Snape's more brooding brow. Her style of dressing could also be an interesting mix, with a touch of Bellatrix's flamboyant dark robes and Snape's more practical and somber attire.
She could inherit Hinata's long, dark hair and Naruto's bright blue eyes. Her appearance might also be influenced by her personality. If she's more like Naruto, she might have a wilder look to her hair, and if she's more like Hinata, she'd have a more reserved and elegant appearance. Also, she might have Naruto's tan skin tone combined with Hinata's delicate features.
One possible storyline could be that Naruto, during his training to become Hokage, seeks advice from Kurenai. As they spend more time together, they start to develop feelings for each other. Kurenai could see Naruto's determination and be drawn to his positive attitude. Naruto, on the other hand, might be attracted to Kurenai's wisdom and grace.
It would change the storyline in many ways. Naruto's focus would be more on his family with Kurenai and their daughter. He might not be as involved in some of the village politics or big missions. His time would be split between his family duties and his ninja duties. And his daughter could have unique abilities, either from Naruto or Kurenai, which could attract both good and bad attention in the ninja world.
It might be blue like the original Kamehameha but with a bit of Naruto's chakra color mixed in, like a bright orange or yellow glow around it.
It could be something like Sakura, after Naruto's friend. It would be a way to show his respect and friendship for Sakura. Or maybe something related to fire, like Kaen, since Kurenai is associated with fire - based jutsu.
In this fanfiction scenario, Naruto's life would take a different turn. Anko and Kurenai adopting him would mean he has two very different mentors. Anko's carefree and sometimes reckless attitude might encourage Naruto to be more adventurous. Kurenai's nurturing side would give Naruto the love and support he always craved. Naruto would also have a different social circle, being associated with Anko and Kurenai. This could lead to new friendships and alliances within the ninja community. He'd be exposed to different jutsu styles and strategies that he might not have otherwise learned. And most importantly, he'd have a family that truly cared for him.
